This experiment will use a photointerrupter, bandpass filter and Arduino's ADC to perform heart rate measurement experiment. In addition, we will practice using ultrasonic distance measurement module and horn to integrate into a reversing radar.
這次實驗將使用光遮斷器、帶通濾波器與 Arduino 的 ADC,進行心率測量實驗。此外,還要練習使用超音波測距模組與喇叭,整合成一個倒車雷達。
